I know this is probably a stupid question, but I'm kind of new to the whole bass amp thing. I recently bought off of craigslist (for a sum total of $400) an Ampeg B4R head and a SVT-610HLF cab. Now here's the problem. The cabinet is just waaaaaaaay to large for me. It sounds amazing, but I live in an upstairs apartment and I just can't be bringing my amp up and down those stairs every time I want to go to practice. I want to do a trade on craigslist for a smaller Ampeg cabinet but I don't know which ones I should be asking for. Here's what I know about the B4R (specs direct from Ampeg's website): RMS Power Output (2 ohms): 500-Watts x 2 RMS Power Output (4 ohms): 340-Watts x 2/1000-Watts (mono) RMS Power Output (8 ohms): 205-Watts x 2/700-Watts (mono) Preamp: Solid State Power Amp: MOSFET Tone Controls: 3-Band Mid Tone Control: Style/Ultra Mid Graphic EQ: Yes, 9-Band Balanced Line Out: Yes, with Pre/Post, Ground Lift and Level Effects Loop: Yes Preamp Out/Power Amp In: Yes, x Two Dimensions (W x H x D inches): 19 x 5.6 x 15 Weight: 43 Pounds Now I'm looking for a 4x10" cabinet to trade for it. I also know the 610HLF is a 4 ohm cabinet. Like I said, I have NO CLUE what cabinets that Ampeg makes that are smaller and can be used with the B4R. I'm going to assume the B-410HLF can since that's the largest "B" series cabinet that Ampeg makes, but I'm not sure at all. THANK YOU SO MUCH TO ANYBODY WHO CAN HELP ME! I couldn't find very much while googling and I'm not even sure what to search anyway, but I have a feeling you guys would know since you guys know way more than I do. Thanks again in advance!
